Digital Single Band Frequency Shift Repeater

Helios@ Digital frequency Shifting Repeaters (FSR) system designed to solve problems of weak mobile signal, which can expand more coverage than RF repeaters and reduce investment for the areas where fiber optic or dedicated cable is not allowed. The Frequency Shifting Repeater system (FSR) consists of two parts: Donor Unit and Remote Unit. The Donor Unit receives the BTS signal via open air radio frequency (RF) transmission or direct couple closed to BTS, then coverts it from the working channel to transmission channel, and transmits the amplified signal to the Remote unit that will reconvert the signal to the working channel and provide signal to the areas where network coverage is inadequate.

As per the method of receiving BTS signal by the Donor Unit, two types of FSR are available:

   Cable-Access FSR: to receive BTS signal via a direct coupler closed to the BTS (Recommended)

   Wireless-Access FSR: to receive BTS signal via a Donor Antenna


Key Feature

  • Customized working frequency operating supporting all major cellular frequency bands including 700MHz, 800MHz, 1800MHz, 1900MHz, 2100MHz or 2600MHz.

  • Supports all major wireless technologies include GSM, EDGE, DCS, CDMA, UMTS, LTE FDD.

  • Band Selective or Channelized based upon Software Defined Filtering, and BW or number of filters can be tunable or upgradeable by software.

  • Supports upgrading filter parameters in case of frequency re-farming by software.

  • Better out of band rejection than analog SAW filters.

  • LED Indicator and Laptop via IP Web Browser GUI and RJ-45 port for local control.

  • Built-in 2G or 3G or 4G modem as option for remote control.

  • Built-in individual AGC & ALC functions for each sub-band.

  • High working Gain Max. 105dB both for Donor Unit and Remote Unit.

  • Eliminate isolation requirement in antenna installation due to the input and output frequency difference.

  • Max transmission distance between Donor Unit and Remote Unit is 20KM.

  • RF composite power +33dBm to +40dBm for medium & large coverage application.

  • Aluminum-alloy casing with IP-65 protection and cool system without fan.

  • Compact size and light weight, easy to install on wall or pole.

  • Optional GPS disciplined clock to provide an accurate, high-quality, stable synchronizing signal which can keep the frequency offset less than 0.01ppm all the time.


Application

To expand cellular signal coverage of fill signal blind area where signal is weak or unavailable.

  • Outdoor: Airports, Tourism Regions, Golf Courses, Tunnels, Factories, Mining Districts, Villages etc.
